觀測器在現代控制系統中扮演估測無法直接量測之狀態的重要角色,廣泛應用於工業自動化、航太、機器人與車用電子等領域。傳統龍柏格(Luenberger)觀測器雖設計簡便,卻難以應對模型不確定性與外部干擾,且缺乏系統化設計流程,限制實務應用。本研究聚焦於H2與H∞強健觀測器,針對其兩種主要架構:輸出注入模型(Output Injection, OI)與輸出估測模型(Output Estimation, OE),進行設計推導與性能分析,建立一套具系統性與實用性的分類與設計流程。本文運用鏈散射描述(Chain-Scattering Description, CSD)與互質分解等方法推導設計流程,並整合閉迴路特性分析與標準控制架構,協助設計者於初期預測系統性能與選擇適當設計參數。此外,導入迴路成型設計方法觀念與降階策略,發展出兼具性能與可實作性的觀測器設計方法。最終,本研究提出涵蓋數學推導、架構選擇、性能預測與降階實現的完整流程,期望降低H2與H∞觀測器實務導入門檻,提升其在控制系統中的應用效能與可行性。
Observers play a critical role in modern control systems by estimating states that cannot be directly measured, with applications in automation, aerospace, robotics, and automotive electronics. While traditional Luenberger observers are straightforward to implement, they are constrained by model uncertainties and lack a systematic design methodology. This study addresses these limitations by developing robust H2 and H∞ observers, analyzing output injection (OI) and output estimation (OE) models. Using chain-scattering description and coprime factorization, a systematic design and performance prediction framework is developed. The proposed approach integrates loop shaping and model reduction to ensure both robustness and practicality, aiming to lower implementation barriers and enhance observer effectiveness in real-world applications.
